ISRAEL II. lVIURDICK AND CHARLES J. GARE'Y, OF BENTON HARBOR, MICHIGAN.

MONKEY-WRENCH.

T 0 all whom "it may concern:

Be it known that we, ISRAEL H. MURoIoK and CHARLES J. Gamay, citizens ofthe United States, residing at Benton Harbor, in the county of Berrienand State of Michigan, have invented new and useful 1mprovements inlhtonkeyrenches, of which the following is a specification.

This invention relates to wrenches and more particularly to combinationtools of the monkey wrench type.

The object of the invention is to provide a simple, ei'licient andcheaply constructed device which will combine a monkey wrench and pipewrench and to provide ready means for attaching a screw driver or nailpuller.

A further object of the invention is the provision of a movable monkeywrench jaw and a movable pipe wrench jaw, together with means forconnecting the same whereby they may be independently or jointly movableand also providing means whereby either of the jaws may be locked inposition to grip a nut or pipe.

Further objects of the invention will appear as the following specificdescription is read in connection with the accompanying drawings, whichform a part of this application, and in which Figure 1 is a sideelevation. Fig. 2 is a longitudinal sectional view. Fig. 3 is a detailtransverse sectional view 011 the line 33 of Fig. 1. Fig. 1- is a detailside elevation showing an auxiliary pipe gripping jaw mounted inoperative position 011 the movable monkey wrench jaw. Fig. 5 is asideelevation showing the position of the parts when it is desired tooperate upon a large sized nut or square or rectangular object. Fig. 6is a perspective view of the screw driver used in connection with thewrench. Fig. 7 is a similar view of the spike puller.

Referring more particularly to the drawings, 1 represents the shank ofthe device which is provided, upon its opposite ends, with stationaryjaws 2 and 3. The shank is provided on its inner face with a racksurface at and the inner face of the jaws is scrrated or roughened, asshown at 5. Slidably mounted over the rack surface of the shank is amovable jaw body 6 which is held in position thereon by means of ayokeshaped casing 7 which surrounds the shank. This jaw body is providedwith the movable Specification of Letters Patent.

jaw 8 adapted to coact with the jaw 3 and has pivoted within the slot 9a cam lever 10. This cam lever, when in normal position with its handle11 extending at direct right angles to the jaw body, will not be inengagement with the rack bar but when thrown to either direction the camsurfaces 12 and 13, which are serrated or toothed, will engage the rackbar to lock the jaw body (3 or the movable pipe jaw 1 1.

The pipe jaw 14; is removably connected to the jaw body 6 by means of apivoted link 15 carried by the jaw 1i and adapted to engage in thelateral or transverse slot 16 in the jaw body 6. The aw 1+1 is pivotallyconnected to the shank 1 by means of a bell crank rock lever 17 havingits lower end operating in a slot 18 in the shank 1 and its upper endoperating in a slot 19 in the jaw 14. When the jaw 1 1 is opened up itseparates from the jaw i2 and from the shank 1 and when closed it movestoward the jaw 2 and shank 1 simultaneously, the end of the aw 14 beingheld down by means of the pin 20 carried by the jaw body 6 and enteringthe recess in the adjoining end of the jaw 1 1. The pin is held in therecess only when the link 15 is in engagement with the slot 16.

The jaw 8 is shown as provided with a socket or aperture 21 in which apin 22, carried by an auxiliary pipe 28, is adapted to seat, so tosecure this jaw in position, as shown in Fig. 4. hen this jaw is used itwill be noticed that the jaw body has a comparatively slight movement ifthe link or loop 15 is in engagement with the slot 16 and in order toaccommodate the device so as to be operable upon larger sized pipes, thelink 15 is disconnected from the slot and the jaw 14 raised, as shown inFig. 5, so as to permit the jaw body 6 to slide thereunder.

In the drawings, the end of the shank is shown as provided with asquared recess 2% in which the reduced and squared ends 25 of either thescrew driver 26 or the spike puller 27 are adapted to seat and be heldtherein by friction or in any other suitable manner.

When the lever is thrown toward the jaw 8 the jaw lat is locked frommovement toward the jaw 3 and when the lever is thrown to the left thejaw 8 is locked from movement toward the jaw 2.

Having thus described the invention, what we claim as new is 1. A wrenchcomprising a shank, stat-ionary jaws on opposite ends of the shank, amovable jaw slidably mounted upon the shank, a movable jaw pivoted tothe shank, means to removably connect said slidable and pivoted jaws,whereby a movement of one will simultaneously move the other, and meanscarried by one of the jaws for locking both of said jaws againstmovement in one direction when said jaws are connected.

2. A wrench comprising a shank, stationary jaws on opposite ends of theshank, a jaw slidably mounted upon the shank and adapted to cooperatewith one of the stationary aws, a second aw pivotally mounted upon theshank and adapted to operate in connection with the opposite jaw, meansfor connecting said jaws together, whereby a movement of one willsimultaneously move the other, said means comprising a pivoted linkcarried by one of the jaws and a double acting locking device carried bythe slidable jaw for locking both jaws against movement in one directionwhen said jaws are connected.

3. A wrench comprising a shank, stationary jaws on opposite endsthereof, a movable jaw slidably mounted upon the shank, a second movableaw, a bell crank lever for connecting the second movable jaw to theshank, means for removably connecting said jaws together, a doubleacting locking device carried by said first movable jaw and adapted tolock either of the jaws against movement in either direction, and meansfor preventing the end of the second movable jaw adjoining the firstmovable jaw from rising when the second movable jaw is in operation.

In testimony whereof we aiiiX our-signatures in presence of twowitnesses.
